` ly applicable for applying covers to the cores of endlessbelts.

An object of the invention is to provide a machine for applying coversto elongate articles which shall becapable of .winding the covercircumferentially of the article and simultaneously folding its edgeslaterally.

In one of its practicalembodiments, the invention includes a driven discdisposed adjacent a plurality of adjustable'rollers, and in the. planethereof, which rollers are adapted to retain a belt core drivenv byengagement with a peripheral portion of the disc. A strip of adhesivefabric to be applied to the core asa cover therefor is fed between'thelatter and the disc, whilestitching rollers and folding devicessuccessively apply portions of the cover to the core. Any number oflayers of covering material may be appliedin this manner merely bycontinuing the winding thereof on the core.V

As best shown by Fig. 3, the aforesaid bracket supports a motor 24that is provided with a shaft 25 having a clutch member 26 slidablykeyed to its end, as indicated at 27. A second clutch member 30,disposed adjacent the clutch member 26 and adapted to be engagedtherewith. is rigidly mounted on a shaft 31 that is rotatably supportedin bearings 32 and 33 in a housing 34 mounted on the frame plate 23. v

The clutch member 26, on its face adjacent thev motor, is provided witha groove38, in which the forked end 39 of a bell crank 40` pivotedintermediate its ends as indicated at 41 to the bracket 22, is disposed.The opposite end 42 of the bell crank is pivotally connected to avertically depending rod 44, that projects'through an apertured plate 45secured to the bracket. An adjustable spring 46 encircles the rod 44 andabuts Ithe lower of a pair of nuts 47 threaded on the rod 44 and theplate 45 at its opposite ends. Consequently, the spring tends to movethe rod 44 and the arm 42 upwardly, in which event the.

clutch member 26 and the clutch member 30 are separated. Upward movementof the rod is limited by a pair of nuts 48 threaded thereon below theplate 45, one of which rod is in its upper- Referring again to Fig. 1,the lower end of Vthe rod 44 is connected by a turn buckle 49 to a rod50, pivoted at its lower end 51 to a crank 52, which is keyedl on ashaft 53 rotatably supported in a pair of brackets 54 bolted to the base20. A treadle 55, provided on the shaft 53 at its end opposite the arm52, facilitates operation of the clutch member 26. Normally, the clutchmembers 26 and 30 are disengaged, but upon downward movement of thetreadle 55, the member 26 is brought into engagement with the .'clutchimember30, and the motor shaft 25 yand the shaft 31'are operativelyconnected' Vtogether'.

The roller'is resiliently `maintained againstthe headV 113 by a'spring 116 abutting at its upper endA a Vcollarj117secured by aset screw118 tothe pin, and at its lower end a thrustbearing119 abutting the roller.

' The frame' plate 23,'.oppos1te the 1 06 and'onits side adjacentthereto, is provided 'with a vertically extending bar 125 ,securedthereto by bolts 124. This bar'h'as a block 126 at its upper endinclined oppositely to theblock 110 on the bar 106 and having an opening128 inclined oppositely to 'the'open ing 109 in the latter. A pin 127,disposed in the opening 128 and secured therein by a set screw 123,is'provided'on its lower end with a resiliently mounted conical Aroller1-29 and a spring mounting assembly similar to that employed on the pin109. The rollers 114 a'nd'129 are'so mountedrthat'xtheir conicalsurfaces' substantially coincide, respectively,

with. the.verticalvplanesin which `the sides "ot the disc'71 aredisposed, but this relation ofthe rollers/and discmay be varied byadjusting the pins'111 and 127 by their respective set screws' 112 and123".

- :A bar 130, secured against' the outer fend of a stud 145threaded intothe outer side ot the base 79 'of the block 76 by afscrevv .133-

projectingthroughthe bar` and vengaging an n opening in the outer end ofthe stud, is provided with openingsv 131 and 132 on opposite sides ofthescrew 133, which loosely receive-the'fsleeve 95 and the bolt 94.

A laterally extending rod 135, `proj eating atone endithrough the'tramevplate 23 directly' beneathfthe block 76, is securedthereto by nuts136Qand 137' on the rodthat abuts opposite'si'des ofthe-frame plate.V'This rod,

at its vouter end, projects through an apen tured bloclry 138 which is'secured `theretoxby 'a'set screw 139.. The block'138` alsoisaperturedto're'ceive va 'vertically' disposed rod 141, which is securedtherein by a set screw 140. Thelatt'er rod has an offset portion 14 atits lower end extendingparallel to the :rod'f'135,"`which is-'disposedtransversely to Vthe lplaneof butv below the disc 71. 4Inad--diti'on,ithe ext-ended portion L1.42'is reversely bent to provide aloop 143. f f

'An upright'150'securedi by bolts 151 to the upper 'end of the-frameplateV 23 on the side thereof adj acent-y the block 76, has in turn anoffset portion 152A at its upper endto 'which averticallyeXtendinggui'd-emember 154 is `secured by bolts 153 (Figs. land 7 Thislguide member has an elongate vertically dis-v '.posedlsl'ot l155 inwhich Va roller mechanism "156 is 'adjustably mounted.l Thel lattermechanism'includes a stud 157 having a reyduced'po'rtion 158 adjacentits inner endl projectingsthrough' the 'slot 155', and Va shoulder 159abutting'theguide member 154 at the sidesof the slot.l *Thes'tud isvadjustably securedto the guidemember by'a screw 160 having va head 163,extending through a collar'16-1 adjacentthe'guide member', and threaded4into the reduced portion '158fof the stud.V 1n lo'rderto adjust theposition. ot the studl and the." guide 'memberya'V pin 162 or othersuitable instrument, is inserted 'into mitting movement of thel stud andcollar relative to the guide member, `whereafter it istightened'tosecure the studin its newly yadjusted position. f

The stud 157 yis provided with a reduced portion 165 outwardlyof theshoulder 159. and other successively reduced portions 1.66 and 167, thelatter of which terminates in a threaded end 1.68. A collar 169,rotatably supported on the reduced portion 165, is provided with achordally disposed aperture 170, through which an elongate rod 171slidably projects. The reduced portion 166 of the stud in turn supportsthe inner race of a ball bearing 173 which is enclosed within a rollerhousing 174, retained in position by a bushing 175 on the reducedportion 167 of the stud and a `washer 176 against which a nut 177 on thethreaded end 168 of the stud abuts.

As illustrated best by Fig. 1, an arm 183, pivoted at 184 to the lowerportion of the frame plate 23, extends upwardly in the plane of the disc71 and is provided with an arcuate upper portion 185V of slightlygreater curvature than thatof the disc. Normally, the arcuate portion isdisposed concentrically to the disc, but spaced a smalldistancetherefrom and its free end rests the seat 85 provided in theoffset portion 84 of the block 76.

` An angle bracket 188 (Fig. 6) ,having an arm 189 provided with anelongate slot 190, is adjustably secured to the aforementioned arcuateportion 185 by a bolt 191 that projects through a locking washer 192,theslot 190,and is threaded into such arcuate portion. The bracket alsoincludes a cylindrical offset portion 194 having a threaded opening 195in its outer end that receives the threaded end of the bolt 196, thehead, ofwhich is provided with a longitudinally disposed threadedaperture 197. This bolt supports an oscillatory collar 199 disposedagainstthe offset 194, and a roller 200 between its head and the collar.A threaded opening 198 inthe collar 199 receives the threaded end oftheaforementioned rod 171 that has previously beenl described as slidablypassing through the collar 69 mounted on the guide member 154. A plate201, disposed on the periphery of the collar, in spaced relation to theopening 198 and secured to the collar by screws 202, is provided with athreaded opening 204 that receives the threaded end of a radially.extendiugfguide rodv 203. lThe side of the collar 199, next to theroller 200, is provided with a threaded opening 206, extending parallelto the axis'of the collar, in which an angle guide rod 205 is secured bya set screw 207. Thisv rod. at its outer end, extends parallel'to therod 203, but is disposed on they side of the roller 200 oppositethereto.

A bar 208 is adjustably secured to the head of the bolt 196 by a secondbolt 209 which projects through the bar and is threaded into theaperture 197 in the first mentioned bolt. This bar is apertured at itsouter end to receive a pin 211 secured at one end in the aperture by aset screw 210. The other end extends toward the roller 200 and isprovidedl with a reduced portion 212 rotatably supporting a roller 214maintained thereon by a nut 215 on the end of the pin. The pin 211 alsois disposed parallel to the bolt 196 and the roller 214 rotatesthereupon in the plane of the roller 200. It is apparent that theposition of the roller 214 may be varied relative to the roller 200 byvarying the positions of the bar 208 and the pin 21.1.

A second angle bracket 225 (Fig. 4) spaced relative to the bracket 188,is rigidly secured by bolts 226 to the arcuate portion 185 of the arm183 and, like the bracket 188, is provided with an offset portion 228having a threaded opening 229 in its outer end that receives a bolt 231.This bolt rotatably supports a roller 230. A sleeve 238, adjacent thebracket 225 above the offset portion 228, is rotatably secured to thearcuate portion 185 of the arm 183 by a bolt 239 which is threaded intoan aperture-240 in the arm. The sleeve 238, in turn, has an integraloffset arm 242 adjacent its outer end, which is apertured as indicatedat 244 (Fig. 5), to receive an elongate stud bolty 245. The end of thelatter adjacent the arcuate portion 185 of the arm 183,

projects throughV an eye 247v of a vertically i disponed eye-bolt 248and has a washer 249 disposed outwardly of the eye which is engaged by anut 253. The eye-bolt 248 projects at its upper end through an aperturedarm portion 256 of an angle bar 257, which has a depending arm 259secured by bolts 260 to the arcuaterportion 185. Above the arm 256, theeye-bolt has a nut 263 adjustably secured thereon which is adapted tolimit the downward movement of. the eye-bolt, while beneath the arm aspring 266 is coniined between the arm, and a nut 265 adj ustablysecured on the bolt.

The bolt 245, on the side of the arm 242 opposite the eye-bolt 248,rotatably projects through legs 269 and 270 of a U-shape block 268,between which legs it rotatably supports rollers 275 and 276. Theserollers are of sufficient diameter that they project slightly below thebase or bottom side of the block. The bolt 245 is retained in the blockby a head 280 engaging the leg 270.

The legl 270 of the block 268 has on its lower side a bar 285 pivotedthereto by means of a vertically extending bolt 283, which projectsthrough the bar and engages the block. In order to retain the bolt 283in position, but loose enough to permit pivotal movement of. the bar 285thereon, the upper end there 'of has a screw 282 threaded therein, whichAso abuts the'upper surface of the'l'eg270 of the block. The barv285(Fig. 4) hase. portion 286 projecting substantially'I parallel tothe n YI vbolt'245 toward the rollers 275 and'27 6, which istwisted adjacentthe outer side of the roller l 27.5, asindicated at287, to provide avertically. disposedlip 288,.which lip isnormally'disposedlin\sub'stantially` the plane ofthe outer sideof the last mentionedroller. j-'This bar normally ,is maintained vin this positionby a rod294pivotally secured tothe bar,`asin dicated at" 292, and which hasV anormally disposed threadedy portion 296extending through an aperturedplate 299 secured lby ,lbolts-301tothe sideA of the block 268. V Betweenthe'bracket 299 and the pivoted end of the rod 294, the portion 296has anut 302 thereoin'to limit the movement ofthe bar 285 toward therollers275and 27 6, while on yits ,Qouter endv it isprovided with anut 303. A

j thereupon.v A spring 319is disposed in encircling relation to therodbetween thelug 314 and a nut 318 threaded on the lower portion oftherod. y b j The arcuatey portion 185 of the arm` 183 also supports asleeve 330, disposed between f V.the sleeve 238and the roller 200, whichis. -740 retained on the arm by a bolt 331 projecting through the sleeveand engaging a threaded aperture 333 in Vthe arm. Adjacent its outerend, the sleeve is providedwith an. integral voliiset arm 334 thatterminatesin an apertured portionsimilar to the arm 242previouslydescribed-' A block 337, (Fig. 1) of lU-shape like the block 268,i'spivotally secured to this arm by an elongate stud bolt I33'6,which sup-Y Vports pair of rollers 345 similar to the rollers 275 and 276 betweenthellegs of the'V block. An eye-bolt l338, mounted on the outer end voi:V the stud bolt, is secured thereon by a nut 340 threaded von theouter end of the bolt. Like the eye-bolt 248, the eye-bolt 338 extendsupwardly and projects through a bracket 350 (Fig. 1') whichhas adepending portion 351 secured by bolts 352 to ythe arcuate arm portion185.l A nuty 354 on the upper end of the eye bolt is adaptedV to limitdownward movement thereof relative to the bracket 350, while between the'bracket and a nut 355 a spring` 357 isfencircled about the bolt.

l Y An arm 370 of an angle bracket 360 is searm 371 of thebracket hasa'rod 363 rpivotally secured thereto, as indicated at 362. This rod,inturn, `projects through-a lug-365 Vintegral with the` sleeveY 330.A1.The outer end of the rod engages-a nut 367, whereas 'aresilient spring369 thereon is confined between a nut-368 and the lug'365.

A bar 380,-',rigidlysecured tothe lower side of 'the legv ofthe block.vadjacent the armA 334, is provided withan `arcuate portion 381 thatextends oppositelyto the arcuate portion V286 ofthetirst mentioned barY285,.and'inter mediate of its ends is twisted,as indicated at 382, toprovide a verticallyv disposed lip 383, positioned" inthe -planejof theouter side of the roller adj-acent this leg of the block 343. j

Anadjustable bar 390 is pivotally connected at its opposite ends Y391and ..393 to the arm 183 and toy a `hand Vlever 392, respectively.Thehand lever ispivotally connected, as in-v dicated at v394, to theframe plate 23. An eX- tended portion'396ofthe hand leverfon the side ofthe pivot 394 opposite the pivot 393 is adapted to engage a lug395Jsecured by a bolt 397 to the frame plate when the hand leveris inthe' position shown by Fig. 1.*v The arm 183 normally is Iresiliently'maintained in the position shown by this ligurebiy a spring 400, whichengages a recessed collar 401, retained bya bolt 402 on the arm1183, andat its oppositeend encir-cles a lug 405, integral with .the boss 68."VIt is apparent when therhand lever 392 is moved counter-clockwise fromits position shown by Fig.,11, that as soon i as the rod 390 moves abovethe pivot 394, the

spring 400 begins to act to move thearm 183 quickly to its inoperativeposition. However, with the rod390 disposed'below the pivot 394, thespring 400 firmly maintains the eX- tended portion, 396 of the handleveragainst thel lug 395 on'` the frame plate, andthus the arm 183 in itsoperative position.

In the operation ofthe apparatus,the endlesscore of, a belt 410 istrained aboutl the rollers`174, 200 and 230 and between the .guide rods203 and 205 disposed adjacent the roller 200. Also the core is' disposedbetween the lips 288 and 283 of the resiliently mounted bar285 and therigid bar 380, respectively.

VThereafter the arm 183lis moved to its operative position by the handlever 392, wherein the core will be disposed against a portion ot' theperiphery of the disc 71. Thus when the motor 24 is energizedthe disc 71drives the core overl the rollers about which it is'trained. In order tofirmly contactthe core with a substantial portion of the 'disc 71, theroller 214 feo' Vmay be moved toward the disc by adjustment of the bolt209, as will be readily understood. With the corein this position, it isdisposed between the resilient lconicalrollers'114 and 129 with theconicalsurfaces of therollers engaging the sides of the core.v

'In applying an adhesive cover 411 to the f Vcured byV bolts'361 on theupperV surface of j core, it initially is trained through the loop 11:.;

. the. block 337, `whereas a vertically extending 143, over the `sleeve9.5,thebolt 94 and the bar 184, and then stitched to the outer peripheryof -the core adjacent ythe roller 200. -As the core is movedby the disc71, the cover is pulled between the conical rollers 114 and 129, and thelatter stitches the side portions of the cover against the sidesof .thecore. ,Simultaneously with this operation, the lip 383 and the arcuateportion 382 of the bar 380 guide one edge portion of the cover over theinner periphery of the core.y Thereafter, thel lip 288 and the arcuateportion 287 ofthe bar 285 guide the other edge portion of the cover overthe inner periphery of the core and also over the first mentioned edgeportion of the cover. Itis apparent that any ldesired number ofthicknessesof cover may be applied to the core by continuing thewindingofan elongate strip thereover. 1

From the foregoing description, it is apparent that a. machine has beenprovided by means of which a cover may be applied to the vcoreof anendless belt or similar article by circumferentially winding a coverabout the core and simultaneously folding it laterally thereabout. Itisapparent also that as many layers of cover ymay be applied to the coreof the beltor such article as ymay be desired. By reason oftheadjustabilityof the roller '174, the resiliency of the conical rollers114 and 129,and the resiliencyof the bars 285 and 380, it is apparentthat 'covers may beapplied to various lengths and sizes of belts.

yAlthough I have illustrated only one form which the invention -mayassume and have described that form in detail, it'will be apparent tothose skilled in the art that the invention is not so limited but thatvarious modifications may be made therein without departing from thespirit of the invention or from the scope of the appended claims.
